I think why this gentleman means by the bots is that will the Zulu be AI (bots) attacking human British?
And nice work on the mod so far guys!
For the event balancing I would take all the refiners in the server and maybe give on 2 or 3 on the British side and the rest that showed up be in the Zulu, to make sure that everyone has fun each regiment could be on the British side at least once or twice do they alternate each round. For example: 44th and 50th are British one round while everyone else is Zulu, next round 44th join Zulu while the 23rs (which was Zulu before) joins the British for that round. So everyone gets to be British at least once, unless they don't want to.
Oh and a message for james, you new to update your regimental thread roster, I've been waiting for my regiment to be reserved for awhile now, I understand your busy but it would be nice if you could do so.
